In-app Uno diagnostics
DevToolsUno
Inspect the running Uno interface without leaving the application.
Overview
An in-app diagnostics suite for Uno Platform applications with live tree, property, binding, resource, style, event, asset, screenshot, and memory inspection.
DevToolsUno attaches to an Uno Application, Window, or FrameworkElement and opens a dedicated diagnostics shell inside the running app. It brings visual-tree inspection, binding analysis, resource and style exploration, event routes, assets, screenshots, and memory tracking into one keyboard-driven surface.
